VACUUM CLEANING AND HEATING SYSTEM.

Original application filed March 2. 1905,'Serial No. 248.106.

Serial No. 584,587.

Specification of Letters Patent.

Patented Aug. 4. 1914.

Divided and this application filed September States, residing at Milwaukee. in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Vacuum Cleaning and lleating Systems, of which the following is a specification, reference being bad to the accompanying drawing, forming a part thereof.

This invention relates to apparatus designed to remove dust and dirt from floors. walls or other surfaces and from carpets, furniture or the like, by means of a current of air.

The main object of the present invention is to utilize the exhaust steam or other heat ing medium from the vacuum producing means of the cleaning system for other purposes, such as supplying heat for the operation of feed water heaters, radiators and the like.

It consists in the construction, arrangement and combination of parts as hereinafter particularly described and pointed out in the claims.

The drawing shows partly in elevation and partly in section, apparatus embodying the invention.

The apparatus comprises a system of piping represented in the present case by a suction or service main a, and one or more branches 1), having on the several floors or in different apartments of the buildings in which the apparatus is installed, service inlet conneetions 0, provided with valves, for the attachment of tools or cleaners (not shown).

A stationary steam boiler (I, usually located in the basement of the building, is shown as provided with a smoke stack 0 and as mounted in an ordinary brick setting which forms a furnace with a combustion chamber f above and an ash pit 9 below a grate k.

The apparatus is preferably providedwith a primary dust collector or separator i, into which the suction or service main (1 discharges for removing the heavier and coarser refuse or dirt from the air with which it is taken up by the cleanin tools. This dust collector or separator, which is preferably located in the basement of the building or near the furnace, is connected with a secondary dust collector or separator j. by a pipe l and serves to prevent the coarser refuse or dirt drawn with air into tl apparatus from passing on to and clo; glue or interfering with the operation of an tlfililliltfll or ejector l in the pipe k. A pipe I)a '.()nll0(.tS the aspirator l with the boiler I] or with a steam supply pipe a Wall ingr therefrom. The pipe in is provided with a valve 0 for manually shutting off steam from the aspii'ato' and also with an automatic regulating valve 1 operated bv a diaphragm or the like, indicated at I and connected on onehside by a pipe r with the pipe 7.- on the inlet side of the aspirator. or with any convenient part of the apparatus in which vacuum is maintained, the valve 1; and its actuating device g, with their connections. constituting an automatic con trcller or regulator governin the. supplv of steam to the aspirator and the operation of the aspirator in accordance with the varymg demands upon the apparatus and consequent variations of vacuum or service pressure within the system of piping.

A pipe 8 provided with a valve 2. connects the lower part of the secondary dust collector j with the combustion chamber f of the furnace above the grate l1. and a pipe 24 provided with a valve c connects the upper part of said collector or separator with a three-way valve to, one branch of which is connected with a blast nozzle :1 in the smoke stack 0, while the other branch is connected with a blast nozzle 3 in a ventilating flue. waste conduit or other duct Another pipe 2, provided with a valve 3, connects said dust collector or separator j at a point above which dust and dirt are allowed to accumulate therein, with a three-way valve 4, one branch of which is connccted by a pipe 5 with the ash pit g of the furnace below the grate [2, while the other branch is connected by a pipe 6 with a feed water heater or other heating device, represented by a radiator 7.

The apparatus as herein shown and described may be operated in several ways. In case it 'is desired to discharge the exhaust from the aspirator Z directly into the furnace, the valves '11 and 3 are closed and the valve t is opened, and thereupon the {mingled air, steam and dust delivered from valve 1), the exhaust steam and air from which the dust is removed in the collector or separator j, may be discharged according to the position of the three-way valve w from the blast nozzle x in the smoke stack e, thereby increasing the draft of the furnace, or from the blast nozzle 1 in the flue or duct 2, thereby producing a draft in said fine or duct.

By closing the valves s and a and opening the valve 3, the exhaust steam and air may, according to the position of the threeway valve 4-, be discharged through the pipe 5 into the ash pit of the furnace, there; by tending to keep the grate bars cool and to soften clinkers, as well as operating to increase the draft of the furnace and aid combustion, or it may be discharged through the pipe 6 into the radiator or other l'ieating device 7, whereby the heat of the steam is 0 utilized to advantage without affecting the operation or impairing the efiiciency of the cleanlng apparatus.

During the operation of the apparatus in the various ways last described, when the exhaust steam and air are directed into the smoke stack 6, duct 2, ash. pit g or heater 7, the dust accumulating in the collector or separator j, is discharged from time to time into the furnace by opening the valvet.

Various changes in the construction and arrangement of the several parts of the apparatus may be made without departing from the principle and scope of the invention.

Features shown and not claimed. herein are claimed in my co-pendingapplications Serial Numbers 84,585 and 584,586.

Vi e claim:

1. In a vacuum cleaning and heating system, a piping-system having means for attachment to a vacuum cleaner. a steam aspirator in communication with a pressure supply and adapted to draw air and dust therotlu-ough, a dust-collector or separator in .said system, means for supplying steam to said aspirator for operating the same, and a heating-system connected with the exhaust of said aspirator, said system being provided with valves controlling points'of disposition of the exhaust from the aspirator.

2. In a vacuum cleaning and heating system, in combination, a piping-system having means for attachment to a vacuum cleaner, a steam aspirator in communication with a pressure supply and adapted to draw air and dust through the system and to maintain ,a vacuum therein, means for supplying steam to said aspirator, a dustcollector in the exhaust of said aspirator and provided with a collecting receptacle, said collector having a dust discharge in the collecting receptacle thereof, whereby the collected dust is vblown out of the collector on opening said dis'icharge,- and a heater connected with said collector at a point above which dust and dirt accumulate thcrein and receiving the purified air and steam therefronn 3. In a vacuum cleaning and heating system, in combination, a piping-system having means for attachment to a vacuum cleaner, a steam aspirator in communication with a pressure supply and adapted to draw air and dust through said system and maintain a vacuum therein, a steam-generator, including a furnace, adapted to supply steam to said aspirator to operate it, a heater receiving the exhaust of said aspirator, a dustcollector interposed between said aspirator and said heater and having the heater connected therewith at a point above which dust and dirt accumulate in the collectorf and a discharge for sald dust-collector 'ar-* ranged to discharge the dust collected therein into said furnace.

In witness whereof We hereto afiix our signatures in presence of two witnesses.
